SECTIONAL CONCRETE TELEGRAPH POLE.

APPLIOA'IION TILED 131 30211910.

Patented Dec. 19, 1911.

After the pole has been built up to the desired height a washer 2 isplaced upon the top section in the counter-sunk recess therein 'and anut is secured upon the end of the bolt or tie rod for binding the partsof the whole pole together. Any suitable cap as '7 preferably made ofthe same material as the pole section and formed with a recess to fitupon the nut 25 is placed upon the upper end of the pole as illustratedin Figs. 1 and 2.

It will be observed that such a pole can be readily made ofindestructible material and can be built to various heights andaccommodated to various purposes and will form a pole that will not bedecayed.

What I claim is z-- I I l. A composite pole comprising a series ofhollow sections, applied'end to end, a sectional tie bolt passinglongitudinally through all of said sections, turn-buckles connecting theadjacent ends of the tie bolt, the interior diameter of the sectionbeing ample to slip over the said turn-buckle, washers threaded upon thetie bolt and counter sunk in the adjacent ends of the pole sections forpreventing their slipping, and step pieces mounted between some of thesections of the pole.

2. A composite pole comprising a series of end to end hollow concretesections, the inner diaireter being large enough to permit the sectionto slip loosely over the inner connection of the pole, an elongated basesection adapted to extend into the ground a distance and having a cordbolt section anchored therein, other bolt sections extending upwardlythrough the hollow pole sections, adjusting means for connecting theboltsections, step pieces arranged between 501119 of the pole sections,washers slipped upon the tie bolt and having recesses formed therein forreceiving the ends of the said step pieces.

3. A composite pole formed of a plurality of concrete sections appliedend to end and having opposing recesses extending into their meeting endportions, washers interposed between said concrete sections and seatedin the recesses formed in the meeting ends thereof for preventing theslipping of the sections, a sectional bolt extending through theconcrete sections and having adjusting connections for holding the bolt.

sections together, the bore of the concrete sections being large enoughto slip loosely over said adjustable connections, a nut and washer atthe upper end of the pole for binding the parts together and a cap piecefitting over the top of the pole and the said nut and washer forcompleting the structure. In witness that I claim the foregoing I havehereunto subscribed my name this 16th day of December, 1910.
